The comment from confusionnn pretty much covered everything.
1.6 was the last confirmed update, this could be the last update but could just as well just be a break. For now, CA wants to work on his other projects like Haunted Chocolatier first, before coming back and adding anything to stardew
That's part of why the 1.6.9 update is taking so long, with a lack of followup updates it needs to be as thorough, bug free, and mod supported as it possibly can before release
